WRENCH.

Application filed July 16,

To all whom it may concern:

Be it known that I, FRANK C. HAGHENEY, a citizen of the United States,residing at John Day, Grant County, in the State of Oregon, haveinvented certain new and useful Improvements in renches, of which thefollowing is a specification.

This invention relates to wrenches and more particularly to anadjustable wrench to be made preferably of pocket size and adapted foruse with bolts, nuts, grease cups, and other articles that require theuse of the wrench. The main object of the invention is to provide awrench that is easily and conveniently adjusted, and when once adjustedto remain so until readjusted, and in order to provide for the certaincontinued adjustment, there is arranged a locking means which preventsaccidental relative longitudinal movement of the jaws of the wrench,while at the same time permitting a degree of pivotal movement of onejaw relative to the other.

The main object of the invention, and other objects that mighthereinafter appear, are attained by the embodiment of the inventionillustrated by the following description and the accompanying drawingsforming a part of this specification.

In the drawings;

Fig. 1 isa side view in elevation'of the wrench as it appears in anadjusted position ready for use;

Fig. 2 is a view similar to Fig. 1, the movable jaw of the wrench beingshown in section to entirely disclose the stationary jaw;

Fig. 3 is a view in elevation showing the position of the movable jaw inposition for longitudinal movement relatively to the stationary jaw foradjusting the wrench;

Fig. 4 is a top plan view of the wrench showing the locking bar indotted lines when in position to permit of the adjustment of the wrench,and in full lines when in position to prevent accidental longitudinalmovement of the jaw;

Fig. 5 is a sectional view on the line 5 5 of Fig. 1;

Fig. 6 shows side and end views of the pivot pin; and

Fig. 7 is a detail plan view of the looking bar;

Fig. 8 is a detail section on the line 8-8 of Fig.1.

Referring to the drawings in detail, the reference character 10designates the Shank 1923. Serial No. 651,926.

of the wrench having at one end thereof the ring handle 11, and at theother end, the head or jaw 12. The shank 10 is provided with alongitudinally arranged series of holes 13 connected by slots 14 for apurpose which will hereinafter appear.

A movable head or jaw 15 cooperates with the fixed head or jaw 12, thejaw 15 being provided with a shank 16 of channel shape, said shank 16being mounted on the shank 10 and head 12 in slidable and pivotalrelation thereto. An opening 17 is provided in each side of thechanneled shank 16, said openings being in alignment, and a pivot pin,shown in detail. by Fig. 6 and designated generally by the referencecharacter 18 passes through the opening 16 and through one of the holes13 in accordance with the position of the shank 16 longitudinally of theshank 10, the spacing of the jaws 12 and 15 of the wrench beingdetermined by the selection of the hole 13. v

The pivot pin is provided with a reduced flat portion 19 to permit thepin 18 to pass from hole to hole through the slots 14 when the pin isturned so that the flat sides of the portion 19 are parallel with thewalls of the slots, as is obvious. When the shank 16 is in adjustedposition, the wider sides of the reduced portion-will be disposed asshown more clearly by the dotted lines in Fig. 2, and longitudinalrelative movement between the shanks 10 and 15 is thereby prevented.

The pin 18 is so disposed in the open ng 17 in the channeled shank as tobe turned when the head 15 is turned. For instance, when the head 15 isin the position shown by Fig. 1, the wider sides of the portion 19 ofthe pin are disposed vertically, as shown by Fig. 2, and when the head15 is in the position shown by Fig. 3 the wider sides of the pin portion19 are disposed horizontally so that the head 15 and shank 16 may beadjusted longitudinally of the shank 10 in order to properly space thewrench jaws to suit the given work in hand. After the wrench jaws areproperly spaced, the head 15 is returned to horizontal position and thepin 18 positioned in the hole 13 which thus acts as a bearing for thepin and prevents the longitudinal relative movement of the two mainwrench parts, the heads 12 and 15.

From the description thus far given it is apparent that it would bedesirable to provide a locking means to prevent the head 15 from turningaccidentally so as to disturb use of the wrench.

the adjustment of the jaws. Accordingly, I have provided a locking meanscomprising a bar 20 pivoted on a pin 21 which ismounted in one side ofthe channeled. shank 16, as clearly shown by Fig. 5, the bar 20 beingcapable of moving through a slot 22 provide in the channeled shank 16.The bar 20 permits of a degree of movement of rotation be tween theheads and 12 as is desirable, but prevents the head 15 from turningsufliciently to be moved longitudinally of the stationary head 12 andshank 10. WVhen the bar is in position normally to prevent sufiicientturning of the head 15 to enable longitudinal movement thereof, it isobvious that accidental disturbance of adjustment of the jaws isprevented. Fig. l clearly shows the position of the fiat bar 20 toprevent undue turning of the shank 16, and in dotted lines in thisfigure is shown the position of the bar 20 when it is desired to movethe head 15 to the position shown by Fig. 3 when it is desired to movethe shank 16 longitudinally of the shank 10 for respacing the jaws ofthe wrench.

To enable the rapid adjustment of the wrench from hole to hole, there isprovided near each hole 13 a groove or depression 23 with whichcooperates a small rib 24 on the inside of the channeled shank portion.It will be easily understood that there are a plurality of such ribs forcooperation with the grooves 23.

The jaws 12 and 15 are provided with work gripping surfaces 25 and 26which are preferably toothed and which. incline at ditl'erent angles topermit of fine adjustments of the relatively movable parts so that theaws may accurately fit any work to which the Wrench may be applied.

From the preceding description it is ap parent that I have provided anadjustable wrench that may be securely locked in adjusted position sothat there can be no longit udinal movement of the movable aw while atthe same time normal turning movement of the movable jaw is permittedand limited to the desired extent. The means for locking the wrench inadjusted positionis exceedingly simple in'both construction and'OPGl'iiflOll and permits of the rapid and aceurate'adjustment of thewrench for dilferent kinds of work. Other advantages of the particularconstruction will 'be apparent from the description and from thepractical 'f 'VVhile' Ihave shown the preferred embodiment of theinvention, it is to be underonly, the invention is not to be consideredas limited thereto except within the scope of the appended. claims.

Having thus described my invention, which I claim and desire to secureby Letters Patent of the United States is:

l. A wrench comprisinga stationary memher having a shank portionprovided with a series of longitudinally spaced holes connectedtogether, by slots, a movable member having a channeled shank slidablypositioned on said stationary shank and provided with aligned openingsin the sides thereof, a pivot pin passing through said aligned openingsand positioned in a predetermined hole in the stationary shank, saidpivot pin having a reduced portion to permit of its passing through saidslots from hole to hole When the wrench is to be adjusted, and a lockingbar pivotally connected to said movable member and cooperating with saidstationary member to prevent accidental longitudinal movement of themovable member.

2. An adjustable wrench comprising a- .stationary member having a shankprovided with holes longitudinally spaced, adjacent holes beingconnected by slots, a movable member having a channeled shank inslidable relation with said stationary shank and provided with alignedholes in the sides thereof, a pivot pin passing through said holes andpositioned in a predetermined hole of the stationary shank, said pivotpin having a reduced portion adapted to be brought into alignment with aslot between adjacent holes wlu-nreby the movable member maybe movedfrom hole to hole for adjustment longitudinally of the stationary shank,and a bar pivotally connected to said movable member and cooperatingwith said stationary member to limit the pivotal movement. of the tormerwith respect to the latter.

3. A wrench having a stationary member, a movable member provided withaslot slid ably and pivotally mounted onsaid stationary member, andmeans for limiting the pivotal movement of the movable member comprisingabar pivoted within said slot in the movable member and movable intoalignment with the stationary member and out of alignment therewithtransversely through said slot.

4-. A wrench comprising a stationary member, a movable member, means forpivotally connecting said members together, said movable member having aslot therein, a pin mounted in saidmovable inember-and'passingthroughsaid slot, and a bar journalled on said pin and swingable throughsaid slot transversely of said movable member'for controlling thepivotal movement between the stationary and movable members,
